Did you catch Jennifer Lopez's outfits on American Idol last week? The judge sparkled from behind the judges' table, and we have all of her outfit details here just for you! For Wednesday's 21st Century Song competition episode, Lopez wore loose silk sparkle box shape tee by Madewell, available online at Madewell.com for $295 (shown). The following night, she fought back tears as contestant Stefano Langone got voted off in a black textured Roberto Cavalli dress, and she accessorized with a stack of bracelets and boots by Christian Louboutin. Stylists Mariel Haenn and Rob Zangardi put together the looks. Cute!
